Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542300, here are decompositions:
- 19 + 31542281 = 31542300
- 67 + 31542233 = 31542300
- 71 + 31542229 = 31542300
- 103 + 31542197 = 31542300
- 137 + 31542163 = 31542300
- 151 + 31542149 = 31542300
- 197 + 31542103 = 31542300
- 233 + 31542067 = 31542300
Showing the first eight; more decompositions exist.
